CAR WHEEL AND AxLE.,

SPECIFICATION forming part of Letters Patent No. 347,119, dated August 10, 1886.

Application filed January 18, 1886. Serial No. 188,918. (No modcLi To all whom, it may concern,.-

Be it known that I, WILLIAM MALAM, a subject of the Queen of Great Britain and Ireland, residing at Edgemoor, Delaware, have invented certain Improvements in Car Vheels and Axles, of which the following is a specification.

My invention consists of Acertain improvemeut-s in the construction and application of detachable journals for railroadcar axles, one of the features of my invention beingl the use of such detachable journals in connection with the combined wheel and axle for which Letters Patent'of the United States No. 329,180 were granted to me on the 27 th day of October, 1885.

In the accompanying drawings, Figure 1 is a longitudinal section of a car-wheel and part of one end of the axle constructedv in'accord! ance with my invention; Fig. 2, a section on line 1 2, looking in the direction of the arrows, Fig. 1; Fig. 3, a perspective view of the jour-4 nal detached from the axle; Fig. 4, a perspective View of the end of the axle to which the 5 journal is t0 be applied; Fig. 5,'alongitudinal section of a car-wheel and part of the axle, showing my invention in a modified form; Fig. 6, a section of Fig. 5 on the line 3 4, lookingin the direction of the arrows; and Fig. 7, a view showinga further modification ofmy invention. The main feature of the invention set forth in my patent abovealluded to was the combination of the body plate-or plates of a carwheel with an axle having a wheel-hub formed integral therewith and presenting a seat or seats to which the body of the wheel was bolted.

In the axle shown in my former patent the journal formed part of the axle; but it is advisable in many cases to make the journal independent of and detachable from the body of the axle, so that it can be removed when worn or otherwise defective and replaced by a new one without discarding the entire axle. For this reason, in constructing my present axle, I provide the body Aof the same with aiiange, a, and construct the .journal B with a corre'- sponding flange, b, which is secured to the flange a by bolts d, which also serve to secure a plate or plates ofthe Wheel-body. v As shown in Fig. 1, the wheel-body consists ing secured to the outer face of the flange b of the journal by means of the bolts d, which pass through said plate and through'both flanges a and b. In order to assist these bolts in resisting the lateral and torsional strains to which the journal is subjected, I provide, the inner face of the flange b with a dovetailed rib or projection, i, which is adapted to a similarlydovetailed recess, m, in the outer face of the ange a of the axle-body, and thus forms a key, the construction of these parts being fully shown in Figs. 3 and 4. The arrangement of rib and recess may, if desired, be reversedthat is to say, the rib may be formed on the flange a and the recess in the flange b,- or a separate key, adapted to recesses in both anges, may be used, as shown in Fig. 7, and Where torsional strainsonly are to be resisted by the key the latter need not be dovetailed or undercut. The construction of the wheel may also be modified in other respects without departing from the main feature of my invention. For instance, in Figs. 5 and 6 I have shown a wheel and axle in which the key is dispensed with, and in which the inner plate, f, of the wheel-body` is in the form of a disk, the central portion of which is clamped between the fianges a and Z), the outer plate, f", being clamped to the outer face of said flange b, and both sets of securing-bolts d and g passingA through both plates and both iianges.

Ido not desire to claim, broadly, an axle having a detachable journal, as this in itself is not new; but

I claim as my invention 1. The combination of the body portion of the axle and the detachable journal, both having flanges which unite to form a wheelhub, inner and outer plates constituting a ,wheel'- body, and bolts whereby said plates are secured to the wheel-hub, some or all of the said bolts also serving to secure together the fianges formi ng said hub,all substantially as specified.

2. The combination of the body portion of 1 the axle having aiiange, a, with outer project ing flange, h, a detachable journal having a flange, b, theplates f f ofthe wheel-body, bolts g, whereby the inner plate, f, is secured to the llange 71, and bolts (l, whereby the outer plate7 billed a flanged body portion, a flanged and detachable journal, and securing-bolts, one of 15 j", is secured to the ilauge b and said llauges a Said llauges havinga projecting key adapted and b are secured together, all substantially as 5 specified.

3. A railrofuhear axle in which a llanged body portion aud a llanged and detachable journal are combined with securing-bolts and willi au undercut keywhieh aids Said bolts iu 1o preventing longitiulinal separation ofthejournal from the axle-body, all Substantially as specified.

4. A railromlcar axle in which are comto a recess in the laee of the other llauge, all substantially as specified.
